光电经纬仪异面交会测量及组网布站优化设计

提出了一种基于空间两异面光轴公垂线估计目标真实位置及组网布站站址几何的优化设计方法.通过光电经纬仪观测目标方位角、俯仰角和基线长度,计算两光轴在待估目标上的两交点,得到目标位置的公垂线.依据两台光电经纬仪的测角准确度作为权系数,估计目标真实位置.通过误差仿真及定位准确度分析,研究了组网测量中交会角、方位角、高低角和基线长度对定位准确度的影响.

Measurement Method and Location Optimization of Multi-Photoelectric Theodolite for Positioning of Aviation Weapons

In order to improve positioning accuracy and data reliability, multi-photoelectric theodolite are grouped for positioning aviation weapons. A new positioning method based on common vertical-line of the intersection of two different planes and location optimization of multi-photoelectric theodolite are introduced. Azimuth angle and pitch angle are obtained by photoelectric theodolite.Crossing points of two optic axis on the tracking target and common vertical line are deduced.And introducing angular accuracy of photoelectric theodolite as weight, the target actual position can be estimated precisely. Continually, based on the error simulation and accuracy analysis, the relations between positioning accuracy and influence parameters, such as the intersection angle, azimuth angle, pitch angle and baseline length, are studied.
